3 DELMHORST C-2000! Read Calibration Check Button # Set-Point Button $ Scale Button C-2000 FEATURES hdesigned to check the moisture content in lint cotton and seed hresistance technology recognized around the world as the most accurate method for measuring moisture. h Averages up to 100 accumulated readings h 4% 16% moisture range on lint cotton h 6% 20% moisture range on seed cotton h Digital readout h Includes (1) 9-volt battery h Proven microcontroller circuit h One-year warranty h 60 years of proven quality, accuracy and service 2

4 BUTTON FUNCTIONS! Read: Reads the %MC Check: Checks the meter calibration. Displays the average of up to 100 accumulated readings; displays the highest stored reading; erases the readings from memory. # Set-Point: Displays the current set-point. Also acts as an arrow (scroll) key to increase the set-point value in 1% increments. A buzzer will alert you if the meter reads higher than the selected %MC value. $ Scale: Displays the meter scale as #1 (Lint) or #2 (Seed) cotton and acts as a toggle to change between the two scales. Also acts as an arrow key to decrease the set-point value. CHECK CALIBRATION hpress the calibration check and read button! simultaneously. Meter is in calibration if it displays 11.1%, ±.2, regardless of the scale setting. When checking calibration, there is no need to disconnect the external electrode. If you check the calibration and the display does not read 11.1, it is likely an indication of a low battery. If this occurs, change the battery immediately. Continued use with a low battery may cause the meter to go out of calibration.if you have a fresh battery and the instrument still does not indicate an acceptable calibration, return it to DELMHORST for service. See Service for Your Meter section. When the battery is replaced, the meter displays its software version for one second and then turns itself off. After replacing the battery, you must reset the meter as described in the Resetting the Meter section. 3

5 TO SET THE SCALE Set the scale for #1 Lint Cotton or # 2 Seed Cotton. hto change the scale, press the scale button $. The meter will display the current scale for one second. hpress and hold the scale button $ to toggle between the two scales. hrelease the scale key $ to stop at the desired scale. Changing the scale will automatically reset the set-point value to the default setting for that particular scale. Default settings are as follows: Lint Cotton 7% Seed Cotton 12% TO CHANGE THE SET-POINT hto change the set-point value press the set-point button #. The meter will display the current set-point value for the scale you have chosen for one second. hto scroll forward to a higher value for that scale hold the set-point button # while the current set-point is displayed and scroll to the set-point value desired. hto scroll backward through the set-point values, press and release the set-point button #. Within one second, press and hold the scale button $. Continue to hold the scale button $ and the set-point will decrease. hwhen scrolling in either direction, release the button to stop at your desired set-point. ha buzzer sounds if the meter reads a %MC higher than the set-point. 4

6 INFORMATION ABOUT YOUR READINGS The meter will accumulate up to 100 readings. After all 100 readings are stored it will not add new readings until the memory has been cleared. It will also continue to display the average of all 100 readings as a reminder that the memory is full. hto add a reading to the sum of all the previously stored readings, release the read button! within 2 seconds. When taking and storing readings for a specific material, be sure to clear the meter before moving on to the next scale if you do not want to group all of the readings together. Moisture content of the samples is the primary factor affecting meter readings. However, readings are also affected by the following: htype of cotton harea where it is grown himpurities hcompaction (density) around the electrode surfaces htemperature of the sample In order to minimize the effect of these factors and improve the repeatability of the meter readings, keep in mind the following points: huse samples with minimum of impurities. hoptimal accuracy may be obtained if meter readings are checked against %MC by means of properly run oven tests on the particular product being tested. TO CHECK THE ACCUMULATED READINGS This feature displays the total number of all accumulated readings for the given material you have chosen, the average of those readings, and the highest stored reading. hto view the readings, press and release the calibration check First the meter displays the number of accumulated readings for one second, then the average of those readings for two seconds. Then it displays the highest stored reading for two seconds. The total cycle time is five seconds. 5

7 hto keep the accumulated readings in memory release the calibration check before the total cycle time is complete. hto erase readings, hold the calibration check for more than five seconds. The total, average and highest readings will be displayed as above, followed by a zero to indicate all readings have been erased. TO RESET METER hpress and release the calibration check hwithin one second, press and hold the scale The meter will display a reset sequence as follows: 121, 8, 1.1, The last number, 11.1 is a calibration check. hresetting the meter clears the memory and restores default settings. APPLICATIONS Testing Lint Cotton hattach the #52-E/C Sample Cup Electrode to the connector on top of the meter. hset the scale for (#1) Lint Cotton and select a set point. hplace a small quantity of cotton in the sample cup. Press the cotton firmly into the cup with your finger. The cotton sample in the cup should be overflowing during the test, even while you are pressing it with your finger. hpress the read button! and read the moisture content on the display. The meter displays the %MC for two seconds. Readings below 4% lint cotton will be displayed as a negative number. Readings above 16% lint will be displayed as a blinking 16.2%. Both the underrange and overrange readings should be disregarded. They will not be added to the accumulated readings or used in calculation of the average or highest reading. 6

8 Testing Seed Cotton hattach the #52-E/C Sample Cup Electrode to the connector on top of the meter. hset the scale for (#2) Seed Cotton and select a set point. hplace a small quantity of cotton in the sample cup. Press the cotton firmly into the cup with your finger. The cotton sample in the cup should be overflowing during the test, even while you are pressing it with your finger. hpress the read button! and read the moisture content on the display. The meter displays the %MC for two seconds. Readings below 6% seed cotton will be displayed as a negative number. Readings above 20% seed cotton will be displayed as a blinking 20.2%. Both the extreme low and extreme high readings should be disregarded. They will not be added to the accumulated readings or used in calculation of the average or highest reading. Tests made on seed cotton may not be as accurate as those made on lint cotton. This is due to the fact that the seed cotton sample is obviously made up of lint and seed, and the quantity of seed may vary from sample to sample. Also, the moisture content of the seed is usually higher than that of the lint. When testing seed cotton, direct contact is still made with the cotton fiber only and not with the seed of the sample. Variables in quantities and moisture content of the seed, during calibration and in field tests, may affect the accuracy and repeatability of the meter readings. The seed cotton scale gives an indication of total moisture content (the moisture content of the seed and the lint in a sample as determined by oven tests) in the seed cotton sample. This may be of interest only in buying and selling seed cotton where some consideration may be given to the weight relationship between moisture content and dry matter. 7

9 Testing Baled Cotton hslide the plastic spacer over the #491 contact pins from the bottom of the pins, mount the pins in the chucks and tighten the set screws. (The #491 contact pins are not inserted into the chucks for shipping purposes). hattach the #30-E/C Electrode to the connector on top of the meter. hset the Scale to #1 Lint Cotton and select a set point. hinsert the electrode pins into the bale and press the read button!. hplace the pin spacers near the tips of the pins when contact is first made with the bale. This helps to keep the pins parallel as they are forced into the bale. The #491 contact pins are insulated, except for 1-3/4 at the tip. The insulation helps to identify the area of moisture, since the reading is obtained from the tip of the pin. Keeping track of moisture readings as the pins are pushed into the bale will give an idea of the uniformity of moisture distribution in the bale. Higher moisture readings near the surface are an indication that the cotton has been exposed to higher moisture after baling. The C-2000 gives accurate results on normally compressed bales. If the bale is loosely packed, the meter will read lower than the actual moisture content. If the bale is very tightly packed, the readings will be only slightly higher than normal, and as a rule, no correction needs to be made. Well-conditioned material will give uniform readings; however, material that is baled before it is dry will show a wide range of moisture content. Several tests should be made on each bale, and you should note the average and the highest readings of these tests. Testing Yarn hconnect the #37-E/C multi-pin electrode to the connector on top of the meter. hset the scale to #1 lint cotton and select a set point. hinsert the electrode pins into the yarn and press the read button!. 8

10 Temperature Correction The basic calibration assumes the cotton temperature to be 70 F. For best accuracy, apply a temperature correction if the cotton temperature is outside the range of 60 F to 80 F. Make a correction of approximately 1.0% for every 20 F. The meter will read higher than the actual moisture content as cotton temperature increases, and will read lower as cotton temperature decreases. Example: At 70 F, a reading of 7% indicates actual %MC of 7%. At varied temperatures, meter readings will vary as follows: Cotton Temperature Meter Reading Actual %MC 110 F 9.0% 7% 50 F 6.0% 7% CARE OF YOUR METER To keep your meter in good working order: hstore your meter in a clean, dry place. The protective carrying case provided is an ideal storage place when the meter is not in use. hchange the 9-Volt battery as needed. Continued use with a low battery may cause the meter to go out of calibration. hclean the meter, contact pins, and probes with any biodegradable cleaner. Use the cleaner sparingly and on external parts only. Keep the cleaner out of the external connector. DO NOT IMMERSE THE METER OR ANY ELEC- TRODE IN WATER. hremove the battery if the meter will not be used for one month or longer. 9
